No, you have it right. I tried quite a few times years and years ago, but because I listened to the pet shop and fed them on liquifry, then powdered flake and didn't know how important water changes were, no more than 5 survived to adulthood per spawn. I gave up trying, as I thought it was too hard with too few results. My sister, who shared a unit with me when I was trying to breed bettas the first time around, thought that I must have bred a dozen pairs to get the quantity of fry I have this time
I'm sure Jeckle will forgive you, but Heckle is mad you thought he was inky
And, yes I am proud! If I can do it, ANYONE can...
